Product ID: 20418031 – Hydraulic Retaining Ring (Discontinued)

Description:
This component is a hydraulic retaining ring designed for use in the high-pressure intensifier pump assembly of waterjet cutting systems . Its primary function is to securely lock and position critical internal components (such as seal heads, hydraulic bushings, and plunger assemblies) within the cylinder housing, preventing axial displacement during operation . It is typically manufactured from hardened spring steel to withstand ultra-high-pressure conditions .

IMPORTANT DISCONTINUATION NOTICE:
This item (20418031) has been discontinued as part of an antiquated assembly. The manufacturer has replaced this part with Item Number SP05118716 .

Applications:

• Used within the hydraulic section of waterjet intensifier pumps to retain seals, bushings, and plunger assemblies 

• Fits specific high-pressure waterjet pump models, including the Streamline SL-IV and PRO-III series (operating up to 90,000 psi and 125,000 psi respectively) 

• Essential for maintaining structural integrity under ultra-high-pressure operation 

Features:

• High-Strength Material: Typically manufactured from hardened spring steel or stainless steel, providing tensile strength and flexibility 

• Heat-Treated: Subjected to heat treatment processes (e.g., solution double-aging) to ensure fatigue resistance under pressure cycling 

• Precision Fit: CNC-formed to tight tolerances for a perfect groove fit 

Maintenance:

• Replacement: Because this part is discontinued, the entire assembly must be upgraded to use the replacement part SP05118716 . Do not attempt to source the old part if it is no longer available.

• Inspection: If the existing ring is still in use, check for cracks, deformation, or wear. A damaged retaining ring can cause seal failure or high-pressure accidents .

• Installation: Proper seating in the groove is crucial; improper installation can lead to component loosening .

• Full Depressurization: Always fully depressurize both the hydraulic system and the high-pressure water system before servicing.
